METALLIC RAILROAD-TIE.

Specification of Letters Patent.

Patented Mar. 28, 1916.

Application led April 3, 1914. Serial No. 829,287.

To all whom it m ay concern.'

Be it kn'own that I, NORMAN M. HENCH, a citizen of the United States.and resident of lVilkinsburg, in the county of Allegheny and State ofPennsylvania,.have invented certain new and useful Improvements inMetallic Railroad-Ties, of which the following is a specification.

My invention has relation to the construction of metallic rail ties andmore particularly relates to the construction of the rail ties used ator beneath the rail joints of a railway track.

One object of my invention is to provide a metallic rail tie of novelconstruction having improved means whereby the rails of a railway trackare more effectively supported and maintained in alinement at the jointsformed by the abutting ends of the track rails.

Another object of my invention is to provide a metallic rail tie havingnovel means whereby bending of the tie plate forming part of my improvedrail tie is prevented and liability of its distortion when the rail tiesare in service avoided and overcome.

Still further objects of the invention will appear hereinafter and bemore fully described in the specification and appended claims.

Referring to the accompanying drawings, forming part of thisspecification, Figure 1 is a plan showing a section of railway trackhaving rail ties as constructed and arranged in accordance with thisinvention. Fig..2 is a plan, on a larger scale, showing in detail themetallic rail tie construction forming this invention. Fig. 3 is alongitudinal side elevation of the tie construction shown n Fig. 2. Fig.4 is an end elevation of the tie construction of Figs. 2 and 3. Fig. 5is a plan similar to that of Fig. 2 showing a modified form of tieconstructed and arranged in accordance with my invention.

In the accompanying drawings referring to Figs. 2, 3 and 4 the numeral 2designates the top flange and 3 the bottom flange of a metallic tie 4 ofI-beam form. As shown, the marginal side edges of the bottom flange 3 ofthe tie have portions 3", 3 which are vbent or curved downwardly forsome distance on either side of a line through the vertical center ofthe rail seats on opposite ends of the tie.

Secured on the top 'flange jacent to one end thereo 2 of the tie adis atie plate 5,

this tie plate extending transversely across the top flange 2 for somedistance on either side thereof. The tie plate 5 is preferably providedwith an upstanding flange G along each side edge thereof, and ispermanently fastened to the top flange 2 of the tie by means of rivets 7extending through registering holes in the tie plate 5 and flange 3 ofthe tie.

Secured to the tie plate 5 at each end thereof by means of rivets 7, 7,is a short tie of the same I-bea1n form as that just described, theseshort sections 9 and 10 being provided to prevent bending or twisting orother distortion of the tie plate when tamping the ties and when theties are in rail securing position in the road bed of the railway trackconstruction of which they form part. The bottom flanges. 3 of the shortsections 9 and 10 have downwardly bent portions 3a, the same as the longtie sections 4.

Rectangular holes 13 are provided in the tie plates 5 for the clip bolts14 and projections or lugs 15 on the under side of the rail clips 16.

On the opposite end of the long section of the tie 4, a narrow tie plate11 is secured by rivets 12 to the upper flange of the tie 4 and the tieplate and upper flange 2 of the tie have registering rectangular holes13"L to receive the clip bolts 14 and the heel or projection 15 providedon the under face of the rail clips 16 in fastening the track rails tothe tie plate and ties to prevent the clip bolts being put in shear whenin service.

In constructing a railway track one tie L such as has been described isused beneath each joint in the track formed by the abutting ends of thetrack rails, so as to rigidly support the abutting rail ends and preventundue deflection of the rails at the joints in the railway track.

Ordinarily the joints in track rails on one side are staggered withrelation to the joints of the track rails on the other side of therailway track, so that one of my improved ties will be used beneath theabutting ends of each pair vof rails on each side of the track.

In cases where the ends of the rails on one side of the track are inline transversely with the ends of the rails at the other side of thetrack, instead of being staggered, a tie plate 5 and two short tiesections 9 and 10 will be used on each end of the intermediate section 4of the tie, in the manner illustrated in Fig. 5. the second tie plate 5being employed in place of the tie plate 11 of the construction shown inFigs. 1, 2, and 3 ofthe drawings.

In building a railway track employing ties constructed in accordancewith my invention, the ties are placed in position on the road bed, oneof my improved ties with the tie pl'ate 5 on one end thereof beingpositioned so as to support the abutting ends of the adjoining rails,17, 18, or 18, 19, or stated in other words, the tie plate 5 of myimproved tie construction is beneath each rail joint 20 of each line ofrails forming a railway track. The intermediate ties 21 used to supportthe rails between the joint ties may be of any of the numerous knownconstructions.

The rails are securely fastened to the tie plates 5 by means of the railclips 16 and clip bolts 14 extending through the openings 13 in the tieplates in the manner as heretofore described.

The track rails are then leveled and the ties are tamped, and whendesired, especially when using my improved tie construction in formingstreet railway tracks, a bed of concrete may be placed around the, tiesto rigidly hold the ties in place on the road bed, instead of employingthe usual rock ballast.

The advantages of my invention will be apparent to those skilled in theart. By the use of a tie plate beneath the joints of the rails which isrigidly secured to the tie and by the use of the short ties at the endsof the tie plates, the joints at the ends of adjacent rails are rigidlysupported against deiection by the weight of the rolling stock and theliability of bending or distorting the tie plates in tamping the ties isprevented and overcome. The provision of the tie plate and short ties ateach end of the tie plate, provides a strong and durable constructionwith a minimum amount of material and at a minimum cost.

Modifications in the construction and arrangement of the parts may bemade without departing from my invention as defined in the claims. Thetie plates may have a plane upper surface instead of having theupstanding ribs or anges as shown. rIhe length of the tie plates and ofthe short tie sections may be varied, the manner of securing the tieplates to the ties may be changed and other variations may be madewithout de arting from my invention as defined in t e appended claims.

1. In a railway tie the combination of a metallic rail connecting memberof I-beam form having a tie plate member secured thereto and forming arail seat, the ends of said tie plateI member overhanging the sides ofthe rail connecting member and short supplemental metallic members ofI-beam form secured to the ends of the tie plate member and extendingparallel to said rail connecting member, said short metallic memberstransmitting the load on the ends of the tie plate member to the roadbed of the railway and thereby preventing bending of said tie platemember.

2. In a railway tie the combination of a metallic rail connecting memberof I-beam form, thin elastic tie plate members on the ends of the railconnecting member forming seats for the track rails, the ends of saidtie plate members overhanging the sides of the rail connecting membersand short supplemental metallic members of I-beam form secured to theends of each tie plate member to extend lengthwise parallel with therail connecting member and adapted to transmit strains on the tie platemember to the road bed of the railway track and thereby prevent bendingof the tie plate members.

In testimony whereof, I have hereunto set my hand.
